[...] What effect does this have? Does this change any pinmuxing at boot? If so, is it just resetting things from what the firmware has set to what we expect it to be? Does it enable card detection on the Pi B? As far as the whole series, I really like the improved description in patch 2, and patch 3 seems like a good idea, too.
